I can't open version 4 of Firefox despite restarting several times. Why?

I was installing Firefox updates when Firefox asked me if I wanted to download and install Version 4. I downloaded the file, saved it and ran it. Each time I try to open Firefox it says: Your computer needs to be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?
After rebooting several times, the problem is still there.

Check that you still have the profile that is listed as Default=1 in the file [http://kb.mozillazine.org/profiles.ini_file profiles.ini]
If profiles.ini is there, but the profile is missing then trash the profiles.ini file and let Firefox create a new default profile.

I can not open more than one firefox page at a time

I usually run 2-3 firefox separate pages during in internet session. Now I can only open one page at a time.

Hello solardave, '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

My toolbar has completely disappeared. I still have the back arrows on the far left, but everything else is just ... gone. I've tried stopping Firefox and restarting several times, but nothing is changing. All the toolbars are checked in the view menu.

July 13th, 2010: My Firefox tool bar has suddenly completely disappeared, except for the back arrows on the left hand side. I've tried stopping and starting Firefox several times, but nothing's changed. All the toolbars are selected in the View menu ... but nothing's visible!

I have stopped too many scripts in Firefox and I can't open any websites in Firefox anymore. I just get blank pages. What do I do now?

3 websites gave me this message:- "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete." I chose to stop the script each time. However I have stopped too many scripts in Firefox and I can't open any website in Firefox anymore. I just get blank pages. What do I do now?

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu) and confirm all upcoming messages.
#Now, uninstall Firefox by following the steps mentioned in the [[Uninstall Firefox from your computer#w_uninstall-firefox|Uninstall Firefox]] article.
'''IMPORTANT:''' On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do '''not''' check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox [[Profiles|user profile data]] will be removed from your computer.
After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:
* '''(On 32-bit Windows)''' ''C:\Program Files\Mozilla Firefox''
* '''(On 64-bit Windows)''' ''C:\Program Files (x86)\Mozilla Firefox''
#Go to the Windows Start menu and click on "Computer".
#In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
#Find the "Program Files (x86)" folder or "Program Files" folder.
#* On 32-bit Windows, double-click the '''Program Files''' folder to open it.
#* On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the '''Program Files (x86)''' folder.
#Look for a '''Mozilla Firefox''' folder. If you find one, right-click it and select ''Delete'' and confirm that you want to move the folder to the Recycle Bin.
Now, go ahead and reinstall Firefox:
#Double-click the downloaded installation file and go through the steps of the installation wizard.
#Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

Can access Yahoo, but can't open Yahoo Mail in Firefox. Can on Internet explorer.

Can access Yahoo, but Can't open Yahoo Mail in Firefox. Can open Yahoo Mail on Internet Explorer. Checked Password.

PROBLEM: This is the error I get when I simply try to open an email in Firefox. File not found Firefox can't find the file at http://us.mg1.mail.yahoo.com/dc/blank.html?bn=555&.intl=us&.lang=en-US. * Check the file name for capitalization or other typing errors. * Check to see if the file was moved, renamed or deleted.
POSSIBLE SOLUTION:
I contacted Yahoo and they had me clear (1) cookies and (2) cache. This did work so that I can now open the emails in Firefox.
COMMENTS:
Yahoo support said "Please rest assured that Yahoo! Mail is properly working as of this time. It would be best if you contact Mozilla Firefox help support. They have the right tools and knowledge with the settings to access Internet Sites like Yahoo! Mail on Mozilla Firefox browser."
I'd like to know what to do to prevent this in the future because I've had this issue twice now in the last few weeks.

'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Can't Open more than One Internet Browser at a Time

I bought a Toshiba laptop this past spring which I use, offline, at the office. i've had a problem with it since the day I hooked it up to the internet the first time. I can't open more than one internet browser at a time. Windows 7. I had need to get online with it today and had forgotten about this problem.
I called Toshiba and they wanted to sign me up to some fee-based service. They said, without checking anything (or even asking me who I am, or what my computer serial number is) that I had a virus. Is there a virus going around that causes this problem? IF so, how could I possibly get it considering I bought this computer in a sealed box?
My AV software does not pick up any viruses. I use Avast.
Can anybody help me?
Thanks.

There's a handy reference for keyboard shortcuts here:
http://windows.microsoft.com/en-US/windows7/Keyboard-shortcuts
That Windows key turns out to be useful, try Windows-D to show the desktop
To open a new browser window, Ctrl-n while in the browser will probably work, or it your browser supports tabs, try Ctrl-t

My iPhone 5c is not being recognized by my mac except to charge it. I'm up to date on all updates and don't know what else to do. I have restarted several times. I have even tried to update my iPhoto and I can't even do that with iPhoto 9.0, but can't.

My Iphone 5c is not being recognized by my Mac computer. I have done all of the upates, restarted several times and I'm not sure what else to do. I have searched and searched and searched and have come up with nothing. Also, my Iphoto can not be updated. I'm still using version 8. something, and it won't update without this update and that update. It needs 9.0 but I can't find that download anywhere. The only one that I can find is 9.1. That won't update. Is there anything that I can do, or should I just bite it and take it to apple to get looked at?

Does iTunes not see the phone?
If not, make sure you're running the current version of iTunes.
If you are running the current version and it still doesn't recognize it, see this: http://support.apple.com/kb/TS1591?viewlocale=en_US&locale=en_US
As for iPhoto, you will have to purchase a newer version. It's not a free upgrade. Or, you can use Image Capture, which is built into OS X, to import the photos.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Can not open pdf forms in Firefox

We have pdf qoutationforms that can no longer be opened whenusing Firefox. (The files opened fine till a few weeks ago). When we click the link it just say stopped in the left corner and after a minute or two Acrobat Reader opens up with the following error message "A file I/O error has occurred. The file connection timed out." The file opens fine in Safari and Internet Explorer.
The two forms are here A file I/O error has occurred. The file connection timed out.

I did try the link, it includes 2 pdf s on that page I did successfully load in firefox, and also downloaded to my computer, so that rules out the site being faulty or the pdf file itself.
* ( small 1MB pdf, it did seem to take a while, maybe the site is slow/busy)
* see [[Error loading web sites#w_interrupted-or-reset-connection]] - Interrupted or reset connection
* Are you still getting the error messages you mentioned in the original post ?
As a workaround for that particular form, I note it is merely there to complete details and gives the option of attaching it to an email. You presumably will already be in a position to do that.
Regarding the '''link you quote and the 2 pdfs '''
# are you able to download them to your computer, can you confirm again that you did that ?
# do those specific pdf files open on your computer with your adobe reader ?
# confirm, or otherwise, do other pdf files open with firefox, ''' when those pdf files are saved on your computer'''
# what version of reader & plugin are you using, is it the latest version (mine is 9, that worked)

'''From what you are saying you appear to have a problem with the plugin.''' If you are unable to open the pdf with firefox when it is on your computer it is unlikely firefox will open that pdf on the webpage

Can't open version 3 documents with version 5

Hello,
My company didn't upgrade me to version 4 so I'm trying to open my version 3 .cp files with version 5. Every time I try to open one, it crashes.
I'm using a different computer (still Windows XP, though) than I had when I last used the version 3 files and am accessing them on a remote server via VPN.
Any ideas? I've tried restarting my computer when it doesn't open and looking for a version 4 to download so I can try opening it that way, saving it, and then opening it in version 5, but I haven't had any luck so far.
Thanks for your help,
Elaine

Hi Elaine
I see this is your second post here in the forums. So it occurs to me that you may be unaware of one of Captivate's "golden rules" that help keep you out of trouble.
That rule?
always, Always, ALWAYS work with projects ONLY when you have them stored on your local C drive.
never, Ever, NEVER EVER consider opening Captivate, then clicking File > Open and navigating to a network drive and try to make edits while the project is on a network.
Sometimes your IT peeps will help you aim the shotgun squarely at your leg and tell you to pull the trigger. They want you to work with your files on the LAN because their precious servers are backed up and your local hard drives typically aren't. It's perfectly fine to store your projects on the LAN if the only purpose is for backup. So consider copying the projects there at the end of each day to satisfy those backup requirements.
Cheers... Rick

I can not open any programs on Firefox that I installed on my other computer after restoring that computer.

I have been a Firefox user for as long as I can remember and do not remember having such problems until I insttaled 34.0.5 I have mostly used Google as my search engine, and sometimes yahoo.
Everytime I try to open say yahoo or google to install them along with many other sites First ir goes to yahoo search instade of google search as I have set as my search engine. I don't like the fact that I no longer have the choice on which search engine I want by default. Nor can I see any means of removing all the others listed Vosteron, that is the first probelem.
I seach for yahoo.com, so I can install it back on the computer, and get this error or alert message with a yellow box in the top left with a crossing guard figue. It says This Connection Is Untrusted. I get it over and over and over, on any sites I have tried opening over the past three days.
I don't know what to do, I've tried about:config and resetting the SSL from 2 to 1. I still get the This Connection is Untrusted. Even tried to add a exception, but it still gives me that annoying message. At this point I do not know it I have some kind of malware, or what. But I have not put many programs back on the computer sense I restored Win 7 onto a new hard drive.
I hope you can help me get this annoying problem fixed once and for all. Otherwise, it Safary.

Reset Firefox to its default state
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.
